    In this commit, we replace references to sock->state SS_CONNECTE
    with sk_state TIPC_ESTABLISHED.
    
    Finally, the sock->state is no longer explicitly used by tipc.
    The FSM below is for various types of connection oriented sockets.
    
    Stream Server Listening Socket:
    +-----------+       +-------------+
    | TIPC_OPEN |------>| TIPC_LISTEN |
    +-----------+       +-------------+
    
    Stream Server Data Socket:
    +-----------+       +------------------+
    | TIPC_OPEN |------>| TIPC_ESTABLISHED |
    +-----------+       +------------------+
                              ^   |
                              |   |
                              |   v
                        +--------------------+
                        | TIPC_DISCONNECTING |
                        +--------------------+
    
    Stream Socket Client:
    +-----------+       +-----------------+
    | TIPC_OPEN |------>| TIPC_CONNECTING |------+
    +-----------+       +-----------------+      |
                                |                |
                                |                |
                                v                |
                        +------------------+     |
                        | TIPC_ESTABLISHED |     |
                        +------------------+     |
                              ^   |              |
                              |   |              |
                              |   v              |
                        +--------------------+   |
                        | TIPC_DISCONNECTING |<--+
                        +--------------------+
